中文摘要 | 利用修正的花粉離體培養方法,分別探討四季蘭各栽培種不同開花日數及開花期之花粉萌芽率,以及冷凍保存90日對‘鐵骨’素心蘭花粉萌芽率之影響,以供四季蘭授粉及花粉保存之應用參考。結果顯示四季蘭不同品種間的花粉萌芽率在不同開花日數間略有差異,‘招財’四季蘭以開花第1~3日採集的花粉萌芽率較佳,‘向日葵’四季蘭則以開花第1~5日採集的花粉萌芽率較佳。四季蘭不同品種間的花粉萌芽率在不同開花期略有差異,其中‘彩虹’四季蘭在6及8月開花期的花粉萌芽率差異不大,‘玉花’四季蘭及‘赤芽’素心蘭花粉萌芽率則以6月開花期較高,8月開花期的花粉萌芽率較低。‘鐵骨’素心蘭之花粉冷凍保存90日後取出回溫並測試其花粉萌芽率,以開花第3日所採集的花粉萌芽率顯著高於其他開花日數採集的花粉。 |
英文摘要 | The objective of this study was to investigate the effects of flowering season, days after flower opening (DAFO) and cold storage on the pollen viability of different varieties of Cymbidium ensifolium. The results could be used as references for cross pollination and pollen conservation in the future. Germination rates were higher for pollens collected on 1-3 DAFO and 1-5 DAFO for the Cym. ensifolium 'Zhao-Cai' and 'Sunflower', respectively. There was no significant difference in the percentage of pollen germination between flowers bloomed in June and August for the variety 'Rainbow', but was higher in June than in August for the varieties 'Yuh-Hwa' and 'Red Bud'. After cold storage for 3 months at 0℃, pollens of the variety 'Iron Bone' collected 3 DAFO showed the highest performancege of germination rate. |
